QUESTION
I have the below requirement . i am trying to run the condition in loop and its taking more time. is there a one time command anything which will not take more time to process a 70 MB file.
Requirement: if @pRECTYPE="SBSB" line contains @pSBEL_MCTR_RSN="XXX" tag then we need to copy and append that to next @pRECTYPE="SBEL record at the end of the line
File :note : in file there will be no blank lines. I have given enter to avoid line continuation
@pRUKE=dfgt@pRECTYPE="SMDR", @pCONFIG="Y" XXXXXXX
@pRUKE=dfgt@pRECTYPE="SBSB", @pGWID="1234", @pSBEL_MCTR_RSN="KX28", @pSBSB_9000_COLL=""
@pRUKE=dfgt@pRECTYPE="KBSG", @pKBSG_UPDATE_CD="IN", XXXXXXXXXXX
@pRUKE=dfgt@pRECTYPE="SBEL", @pSBEL_EFF_DT="01/01/2017", @pCSPI_ID="JKOX0001", @pSBEL_FI="A"
@pRUKE=dfgt@pRECTYPE="SBEK", @pSBEK_UPDATE_CD="IN",XXXXXXXXXXXXXXXXXXX
@pRUKE=dfgt@pRECTYPE="DBCS", @pDBCS_UPDATE_CD="IN",XXXXXXXXXXXXXXXXXXXXXXXXXX
@pRUKE=dfgt@pRECTYPE="MEME", @pMEME_REL="18", @pMEEL_MCTR_RSN="KX28"
@pRUKE=dfgt@pRECTYPE="ATT0", @pATT0_UPDATE_CD="AP",XXXXXXXXX
@pRUKE=dfgt@pRECTYPE="SBSB", @pGWID="1234", @pSBEL_MCTR_RSN="KX28", @pSBSB_9000_COLL=""
@pRUKE=dfgt@pRECTYPE="KBSG", @pKBSG_UPDATE_CD="IN", XXXXXXXXXXX
example :
Before : @pRUKE=dfgt@pRECTYPE="SMDR", @pCONFIG="Y" XXXXXXX
@pRUKE=dfgt@pRECTYPE="SBSB", @pGWID="1234", @pSBEL_MCTR_RSN="KX28", @pSBSB_9000_COLL=""
@pRUKE=dfgt@pRECTYPE="KBSG", @pKBSG_UPDATE_CD="IN", XXXXXXXXXXX
@pRUKE=dfgt@pRECTYPE="SBEL", @pSBEL_EFF_DT="01/01/2017", @pCSPI_ID="JKOX0001", @pSBEL_FI="A"
After:
@pRUKE=dfgt@pRECTYPE="SMDR", @pCONFIG="Y" XXXXXXX
@pRUKE=dfgt@pRECTYPE="SBSB", @pGWID="1234", @pSBEL_MCTR_RSN="KX28", @pSBSB_9000_COLL=""
@pRUKE=dfgt@pRECTYPE="KBSG", @pKBSG_UPDATE_CD="IN", XXXXXXXXXXX
@pRUKE=dfgt@pRECTYPE="SBEL", @pSBEL_EFF_DT="01/01/2017", @pCSPI_ID="JKOX0001", @pSBEL_FI="A", @pSBEL_MCTR_RSN="KX28"
if after SBSB, if there is no SBEL, then that SBSB can be ignored.
what i did is egrep -n "pRECTYPE="SBSB"|pRECTYPE="SBEL"" filename | sed '$!N;/pRECTYPE="SBEL"/P;D' | awk -F: '{print $1}' | awk 'NR%2{printf "%s,",$0;next;}1' > 4.txt;
by this i will get the line number eg: 2,4 17,19
line 9 12 14 will be ignored
while read line do

This requires GNU awk:

One option is with CSS selectors.

QUESTION
Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.
Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS
, and returns those arrays to my destination FormattingWS
. I'm still trying to learn arrays so if the methodology I used to do this isn't proper, be gentle.

QUESTION
I have a dataset that was recorded by observation(each observation has its own row of data). I am looking to combine/condense these rows by the plant they were found on - currently a character variable. All other columns are numerical vales.
EX:
This is the raw data |Sci_Name|Honeybee_count|Other_bee_Obsevrved|Stem_count| |---|---|---|---| |Zizia aurea|1|5|10| |Asclepias viridiflora|15|1|3| |Viola unknown|0|0|4| |Zizia aurea|0|2|6| |Zizia aurea|3|6|3| |Asclepias viridiflora|8|2|17|
and I want:
Sci_Name Honeybee_count Other_bee_Obsevrved Stem_count Zizia aurea 4 13 19 Asclepias viridiflora 23 3 20 Viola unknown 0 0 4I am currently pulling this data from a CSV already in table form. I have been attempting to create a new table/data frame with one entry of each plant species, and blanks/0s for each other variable, which I can then use to c-binding the two together. This, however, has been clunky at best and I am having trouble figuring out how to have each row check itself. I am open to any approach, let me know what you think!
Thanks :D

Answered 2021-Jun-15 at 18:02We can use the formula method in aggregate
from base R
. On the rhs of the ~
, specify the grouping variable and on the lhs, use .
for denoting the rest of the variables. Specify the FUN
as sum
and it will do the column wise sum by group
QUESTION
I am pretty new to python and I am trying to sort through a directory's files that start with 'O0' and copy any string in the text files that has an 'F', 'T', or 'S' in them, and paste, preferably just that string, (but the whole line would still work) in a new text file, preferably on the desktop. It is making the text file, but it is blank, and python does not close the file. Here's what I have so far:
...ANSWER
Answered 2021-Jun-15 at 14:27In the first place you are probably getting an AttributeError
error that append
is not known. Because you try to append your text to the TextIOwrapper (feeds speeds
). You have to use the write
method to append the text to the file content.
Also note that your file is read and written from the current directory, so ./feedsspeeds.txt
. As long as you are not executing this script from you Desktop folder, the file will also not be written there.

QUESTION
I want to import all files from one directory to my sql. But I have to make the same changes to each original .htb file first. The problem with the original file is that
I don't want to import the column headers and the 2nd line because its blank
I need to change \t\t\t\n to only \n so MySQL knows where fields and lines end
I need to remove -----\n because it only has 1 column which doesn't match my tabe (4 columns) Here's how the original .htb file looks like:
Beschreibung\t Kurzbeschreibung\t Einheit\t Wert\t\t\t\n
\n
Hub\t Hub\t mm\t 150.000000000000\t\t\t\n
Bohrung\t Bohru\t mm\t 135.000000000000\t\t\t\n
-----\n
so far I have managed to create a list of all files. My next step would be to write that list to 1 single file which I can then edit. The problem I have is that I get a format issue when I save the list do a file. I want the final file to have utf8 format. this is what I want my file to look like:
...ANSWER
Answered 2021-Apr-13 at 10:47pickle
produces a binary format, which includes per field "header" bytes (describing type, length, and for some pickle protocols, framing data) that are going to look like garbage text if you view the output as text. You can't say "I want it to be pickle
, but not have these bytes" because those bytes are part of the pickle
serialization format. If you don't want those bytes, you need to choose a different serialization format (presumably using a custom serializer that matches this HTB format). This has nothing to do with UTF-8 encoding or lack thereof (your input is ASCII), the problem is that you are demanding a result that's literally impossible within the limits of your design.
QUESTION
This question is related to Azure MSIX Build and Package task only has Release and Debug configurations
We have a WinForms project that has an MSIX installer. Manually, we can successfully create
- An MSIXBUNDLE and deploy it to Kudu
- An MSIX and deploy it to an Azure VM through a VHDX. We have manually convert the MSIX to a VHDX first
We are now trying to automate the build and release process to create the VHDX. However, we are getting a blank screen when the VHDX is mounted using a process that we have already validated. The only thing different is the build method (i.e., MSBuild versus VS Publish).
How do we create a working VHDX in Azure CI Build Pipeline?
Below is the YAML.
...ANSWER
Answered 2021-Jun-15 at 14:26Actually, there is nothing wrong with the YAML. The problem was a delay in the virtual machine loading the VHDX. In other words, wait about 5 minutes once the VHDX is mounted before trying to run the application. I am leaving this here in case anyone else runs into this issue
